28. ARGYRA MINUTA Loew 



Argyra mlnuta Loew, Smiths. Misc. Coll., No. 171, p. 129, 1SG4. 



A small species with the legs and feet wholly yellow, palpi and 

 antennae black. The outer hypopygial lamellae are narrow, rather 

 short, yelloAvish; inner appendages somewhat conical with a bristle 

 at apical point. The male has the joints of fore tarsi as 33-12-8-5-5, 

 their tibiae as 54; the joints of hind tarsi are as 30-24-15-8-6. The 

 female has the joints of fore tarsi as 22-13-9-6-6; those of hind tarsi 

 as 28-22-18-9-8. * 



It is difficult to separate the female of this from that of calcitrans 

 Loew and setipes new species. I give below the length of the joints 

 of fore and hind tarsi of the females of the last two named species 

 as I separate them, for comparison with those of vmiuta. 



The joints of fore tarsi of the female of calcitrans are as 

 33-14-9-6-7, those on hind tarsi as 32-25-18-17-16. The joints of 

 the fore tarsi of setipes are as 42-19-15-9-7, those of hind tarsi as 

 35-35-23-15-9. The palpi in setipes are yellow and large : while in 

 both the other species the palpi are smaller and blackish. 



29. ARGYRA FLAVIPES, new species 



Mate. — Length, 3 mm. Face and front silvery white. Palpi cov- 

 ered with silvery pollen. Proboscis yellowish. Antennae (fig. 15) 

 black; I can s'ee but one hair on the upper edge of first joint: third 

 joint more brown, longer than the basal two taken together, rounded 

 at tip ; arista inserted a little beyond its middle. 



Dorsum of thorax shining green with but little silvery white pol- 

 len; pleurae more black with its posterior edge j'ellow. First ab- 

 dominal segment black; second, third, and fourth yellow, their 

 posterior margins rather widely black: fifth and sixth black with 

 green reflections. Hypopygium (fig. 18) black; its appendages yel- 

 lowish ; outer lamellae somewhat triangular, fringed with long hairs ; 

 inner appendages a little clavate. 



All coxae, femora, tibiae and tarsi wholly yellow, tips of tarsi only 

 a little darker and sometimes the tips of hind femora are brownish; 

 middle femora with one preapical bristle, nearly bare below; pos- 

 terior pair with a row of slender bristles on anterior surface, several 

 of which are longer than the width of the femora. Fore tarsi with 

 their joints as 28-15-9-7-10; joints of hind tarsi as 29-20-15-10-6. 

 Calypters, their cilia and the halteres yellow.
